Math Blocks is a puzzle game for iPhone, iPad, Mac, Windows, Linux and the web. It is built to need nothing from you.

What we collect

Nothing. Math Blocks has no accounts, no analytics, no advertising and no tracking, and it doesn't send any information about you or how you play to us or to anyone else.

What stays on your device

Your progress — the current puzzle, your history of solves and skips, streaks, times and settings — is saved only on your device (in the app's own storage, or in your browser's local storage on the web). Deleting the app, or clearing your browser's data for this site, removes it. It is not backed up or synced by Math Blocks.

Sharing a puzzle

If you tap share, Math Blocks makes a link holding that puzzle (its digits and target) and, if you solved it, your time. It goes only where you choose to send it, through your device's share sheet or clipboard. The link holds nothing else about you.

This website

This site sets no cookies and runs no analytics. Like any web server, the host may keep standard request logs (such as IP address and browser type) for security and operation; they are not used to identify or track visitors.

Children

Math Blocks is suitable for all ages. Because it collects no personal information, it collects none from children either.

Changes

If this policy changes, the new version will be posted on this page with a new date.
